Thread: Series landy fuel comsumption

My mutant tends to return all sorts of values for fuel consumption but then I've changed a fair bit from a standard 186 as you know.

Poking around town tends to return somewhere around 15~20L/100km but that's alot of short shifting and steady driving.

Towing the car trailer tends to make it suffer pulling it back to 40L/100Km @ 80km/hr but the box trailer only makes a difference when loaded with something heavy like gravel.

Before I put the OD in @ 90km/hr it would consume 35L/100km

With the OD engaged @90km/hr it's about 15~18L/100km and @110~120km/hr steady 20L/100km

So if I was to return it to "standard" by clogging up the exhaust with the single outlet manifold and the stromberg carbie feeding I'd probably get a consumption figures around yours Pheonix.


The brother inlaws series 2 with a fresh 2.25 motor, pea rifle sized exhaust, Zenith Carby and Fairey OD does worse than mine with fuel consumption. Somewhere in the range of 25~30L/100Km @ 80km/hr and worse when it gets to 100km/hr.

SIII 109 HT with 179 red Holden: 22-25l/100km
SIII 109 STW with 2.25l five-bearing LR engine 16-17l/100km

Hope this helps...

my '76 S3 still has the original 2.25l with 146000 km on the clock. Has a loose Fairley O/D - cruises at 80-90km/h - the wind drag seems to cut in outside 85km/h that making the engine work a lot harder for any smaller gain

Gets 13l /100km on LRP with Morleys upper cyl added.

... i do though drive basically highway cycle - 46km up the gateway then 46km back home & I don't expect acceleration its not meant to do

It's the colder air down your way that improves the peformance.

What cooler air, it's going to be about 27 here today 8O

I really want aircon in my office [img]style_emoticons/<#EMO_DIR#>/sad.gif[/img]

I just managed to get a better carburettor for my landy with a better mainjet, looks like I might squeeze a little more economy out of the old girl yet [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

Cooler than here. [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

Just be careful to not go too lean to where you burn the crowns out of the pistons. [img]style_emoticons/<#EMO_DIR#>/sad.gif[/img]
